Why is cedar wood used with oil immersion objective?
Cedar wood is used with oil immersion objectives in microscopy because it has a refractive index similar to that of the oil (usually 1.515) used to fill the space between the objective lens and the specimen. This minimizes light scattering and improves image quality by increasing numerical aperture and resolving power.
What are the advantages of the oil immersion objective?
One advantage is that it increases the resolution and clarity of the image, this is very useful for viewing specimens that would otherwise be to small to see without the oil. However it can be very messy to apply the oil and can take time and be rather difficult to clean the slide and the microscope. Moreover the slide could become damaged if vertical movement is used a lot; this is because the work distance between lens and slide is very small.
What are the names of the parts of the microscope that change the magnification?
I. Magnifying Parts 1. Ocular/Eyepiece-magnifies specimens by 10-15 times 2. Objectives: a. Low-Power Objective- 10-15 times-general view of the specimen b. High-Power Objective- 43-100 times-detailed parts of the specimen c. Scanning Lens- 5 times-general view of the specimen d. Oil Immersion Objective- 1000 times-used only for viewing bacteria; needs cedar oil II. Illuminating Parts 1. Mirror- reflects light 2. Condenser- concentrates light 3. Sub-stage Condenser- allows light to pass 4. Iris Diaphragm- controls the passage of light
